Robert Gustafson, the longtime CEO of the former Crescent Credit Union, plans to retire on June 30.

Gustafson became Brockton-based Crescent Credit Union’s CEO in 1993. When the credit union merged with Sharon Credit Union in 2020 – creating Sharon & Crescent United Credit Union – Gustafson became SCU Credit Union’s executive vice president, working as a strategic adviser and focusing on being out in the community, SCU Credit Union said in a statement.

Gustafson started his banking career at Plymouth Home National Bank. During his time as Crescent Credit Union’s CEO, the institution’s assets increased from $160 million in 1993 to $450 million in 2019, according to the statement.

“The goal was always to manage the credit union and staff as effectively as possible and give our members the best service we could,” Gustafson said in the statement.

In addition to the merger that resulted in the now $1.2 billion-asset SCU Credit Union, Gustafson led Crescent through mergers with Uniti Credit Union and Brockton Postal Employees’ Credit Union.

Gustafson is currently on Stonehill College’s executive committee for development and has held various board positions over the years. He plans to continue as a member of the Massachusetts Share Insurance Corp. advisory board during his retirement, the statement said.
